PyQt5 QSpinBox – 获取文本的样式

在本文中，我们将了解如何获取旋转框文本的样式，旋转框有许多可用于其文本的样式，例如 StyleOblique、StyleNormal 和 StyleItalic，默认情况下它的样式设置为 StyleNormal 样式。我们可以借助 setStyle 方法为其设置样式
为了做到这一点，我们将 style 方法与旋转框的 QFont 对象一起使用。

Syntax : font.style()
Argument : It takes no argument
Return : It returns QFont style object but when printed it shows the style value 
 

下面是实现

Python3

# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
 
 
class Window(QMainWindow):
 
    def __init__(self):
        super().__init__()
 
        # setting title
        self.setWindowTitle("Python ")
 
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
 
        # calling method
        self.UiComponents()
 
        # showing all the widgets
        self.show()
 
        # method for widgets
    def UiComponents(self):
        # creating spin box
        self.spin = QSpinBox(self)
 
        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)
 
        # setting range to the spin box
        self.spin.setRange(0, 999999)
 
        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")
 
        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")
 
        # getting font of the spin box
        font = self.spin.font()
 
        # setting style
        font.setStyle(QFont.StyleOblique)
 
        # reassigning this font to the spin box
        self.spin.setFont(font)
 
        # creating a label
        label = QLabel(self)
 
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 60)
 
        # getting style
        style = font.style()
 
        # setting text to the label
        label.setText("Current Style value: " + str(style))
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出 ：
